10 ways epigenetics explains speciation better than NeoDarwinism




Here are 10 ways epigenetics explains speciation better than Neo-Darwinism:

  1. Epigenetic changes can be inherited. This means that they can be passed down from parents to offspring, even if the offspring do not have the underlying genetic mutation. This is in contrast to Neo-Darwinism, which only considers genetic changes that are inherited.

  2. Epigenetic changes can be caused by environmental factors. This means that they can be influenced by things like diet, stress, and exposure to toxins. This is in contrast to Neo-Darwinism, which only considers genetic changes that are caused by random mutations.

  3. Epigenetic changes can be reversible. This means that they can be turned off or on, depending on the environmental conditions. This is in contrast to Neo-Darwinism, which assumes that genetic changes are permanent.

  4. Epigenetic changes can affect multiple genes at once. This means that they can have a more widespread impact on the phenotype than a single genetic mutation. This is in contrast to Neo-Darwinism, which focuses on the effects of individual genes.

  5. Epigenetic changes can occur rapidly. This means that they can lead to speciation in a shorter amount of time than Neo-Darwinism would predict.

  6. Epigenetic changes can be shared by a population. This means that they can spread through a population more easily than genetic mutations.

  7. Epigenetic changes can be adaptive. This means that they can help organisms to survive and reproduce in their environment. This is in contrast to Neo-Darwinism, which does not explicitly consider the role of adaptation in evolution.

  8. Epigenetic changes act outside of  natural selection. This means that natural selection can't act on epigenetic changes, it can only act on mutations.

  9. Epigenetic changes can be a source of genetic variation without mutations. This means that they can contribute to the genetic diversity of a population, which is essential for evolution.

  10. Epigenetic changes can be a mechanism of rapid evolution. This means that they can help populations to adapt to changing environments more quickly than Neo-Darwinism would predict.

Epigenetic changes can provide a mechanism for rapid evolution in response to environmental change.

In conclusion, epigenetics provides a more complete and nuanced understanding of speciation than Neo-Darwinism. It can explain how speciation can occur more rapidly, how it can be influenced by environmental factors, and how it can be adaptive. Epigenetic changes are a powerful force in evolution, and they are essential for understanding how new species arise.

Beyond the Sequence: The Epigenetic "Fingers" That Play the DNA Keyboard

Image
Imagine the keyboard itself is not a standard piano keyboard, but a modular synthesizer, capable of producing an almost infinite array of sounds. The DNA sequence, then, represents the fundamental building blocks of this synthesizer, the raw materials from which all sounds are generated. Epigenetics, our "fingers," manipulates these building blocks, adjusting parameters like volume, timbre, and rhythm, transforming the raw potential of the DNA sequence into a symphony of cellular functions. We can further refine the "fingers" analogy. Consider that each finger represents a distinct epigenetic mechanism: DNA methylation, histone modifications, and non-coding RNA.  DNA methylation, for instance, might be the "index finger," capable of precisely silencing specific genes, like muting individual keys on the synthesizer. Histone modifications, the "middle finger," could represent the ability to adjust the accessibility of the DN...

Why are Christian philosophers running towards Darwin while biologists are "running" away?

Image
As nature reveals the strength of epigenetics and the weakness of Neo-Darwinism, biologists are “running” away from the long-standing accepted theory. In The Federalist , April 2019, Benjamin Dierker reviews “Why one-third of biologists now question Darwinism”: "Current estimates are that approximately one-third of professional academic biologists who do not believe in intelligent design find Darwin’s Theory inadequate to describe all of the complexity in biology.” Dierker continues, “The important note is that these are not ideologues or religious zealots, nor do they propose a god or biblical solution.  Rather, they find problems in the lack of explanatory power of Darwin’s theory in light of modern understanding of mutation, variation, DNA sequencing and more. These expressions of doubt do not reject naturalism or evolution per se, but the rigor of the Neo-Darwinian model for explaining the development of life.” For 40 years, scientists calculated natural se...

Rewriting the Rules: Epigenomic Mutation Bias Challenges Randomness in Evolution

Image
This research challenges the long-held dogma that mutations occur randomly, irrespective of their consequences, by demonstrating a clear, epigenome-mediated mutation bias in Arabidopsis thaliana . The study meticulously unveils how mutation rates are not uniform across the genome but are significantly reduced in functionally constrained regions, particularly within gene bodies and essential genes. This discovery fundamentally alters our understanding of evolutionary processes, suggesting that mutation is not a purely directionless force. "Mutation bias reflects natural selection in Arabidopsis thaliana" This opening statement encapsulates the core finding: mutation rates are not random but reflect epigenetic pressures. The authors demonstrate that mutations are less frequent in crucial genomic regions, directly contradicting the prevailing theory of random mutation. This observation suggests an active mechanism that minimizes deleterious mutations in essentia...
